.To all whom it may concern:

Be it known that L'WILLIAM KAISLING, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Indicating- Switche's, of which the following is a specification.

which is adapted to control a plurality of circuits, which switch has means whereby suitable indication is made as'to the manner in which this switch had been last actuatedl In one form of my invention, which is the form disclosed herein, rality of circuit terminals, the circuit through which is to be controlled by a suitable movable switch element. Thismovable switch element is provided with means so that whenever completing any given circuit, it must be manually held in that position because when released the switch element will return to a non-circuit controlling position. The movable switch element however has a plurality of resting positions. each one indieating which particular circuit closing function the switch element has last been called upon to perform. 1 will explain this form of carrying out my invention as it serves well for illustrative purposes in detail in connection with the accompanying drawing, in which- Figure 1 is a top view of aninclosed switch structure constructed in accordance with my invention; Fig. 2 is a bottom view of my device;'Fig. 3 is a switch structure the casing being removed; Fig. 4 is a similar view showing the parts in analtern'ative position; Fig. 5 is an end view of the structure shown in Fig. 3; Fig.

6 is an end view lookmg'at the opposite end to that shown in Fig. 5; of the device as shown in Fig. 3; Fig. 8 is a sectional view on line a.-a of Fig. 3; Fig. 9 is a top view of the movable switch .element; Fig. 10 is a of the switch locking mechanism, and Fig.

11 is a detail view of a portion of the frame-- work of the device.

My improved switch element consists of a base plate 1 having holes 2, 2 through the agency of which it is mounted within a casing 3 by means of the bolts 1 as shown more Specification of Letters Patent.

invention relates to indicating .SWllZCllBS and is designed to provide a switch I utilize a plu-- hole 21 prbvided therefor.

clearly in Fi 8. The casing 3 is provided with a suitab e cover plate 5 and also carries a layer of insulation 6 so that connectors7, 8. and 9 respectively mounted on the base plate 1 may rest upon the surface of the easing without being short cireuited. Outlets 10 are provided in the shell 3 which are pref-' erably of insulating material and which perreadily over contact-surfaces with which they are t0 coiiperate.

This sleeve 13 also earries a cam 38, which cam is more clearly shown in Fig. 4 as having a slot 19 whose opposite sides are adapted to engage an insulating roller 20' fixedly carried by the switch element 16 by being mounted in the This cam 38 as stated is fixedly secured to the sleeve 13 by being pinned thepeto through the agency of the pins 22 as shown more clearly in Fig. 8. The switch element 1821s stated is insulated from the sleeve 13 and is also prevented from having electrical connection with the cam 38 through the interposition of the insulating bushing 20 This cam 38 is shown also very clearly in dotted lines in Fig. 3 and has a pair of teeth 23 and 24. A bracket 25 fixedly secured to the base plate l'through the agency of studs 26, 26 helps to support the upper extremity of the sleeve 13. The

element 38 also carries a downwardly projecting pin 27 which is adapted to cooperate with a pair of limit stops or .pins 28 to limit the angularmovement of the rotatable The roller 29 is carried 30, which swinging arm by a swmgmg arm is pivotally mounted by being fixedly semounted shaft 31 cared between the base plate 1 and the bracket 25. The bracket 25 has a downwardly extendingarm 32 which holds one extremity of a spiral spring 33, the opposite extremity of cured to the pivotally said spiral spring engaging a stud 3a mounted between the opposite sid le s of the swing ing arm 30. The,. spiijng"33 always holds the roller 29 in engagement with the cam ele- 5 i11ent.;,38 Cl?his'roller thus cooperates with the teeth 23 and 24 and normally holds the switch element 16' in either one of the positions shown in Fig. 3, one position being shown in full lines and the other position being shown in dotted lines.

--N ow whenever pressure is exerted against the handle to push itin a contra-clock wise direction, the switch element assumesthe position shown in Fig. 4, whereupon the 15 roller 29 is pushed outwardly against the force of the spring 33, and when the pressure is released on said arm 14:, the parts are again pushed into the position shown in full lines in Fig. v3. Similarly when pressure is exerted against the arm 14 to push it in a clockwise direction, the switch element 16. is moved clockwise beyond the position shown in dotted lines in Fig. 3 to occupy the position on the opposite side of .the base 25 plate corresponding to the position shown in full lines in F ig. et, at which time .the roller 29 is again held outwardly and when the pressureis released restores the switch element to the position shown in dotted 30 lines in Fig. 3. The switch element is adapted to cooperate with three contact plates 35, 36 and 37, the contact being in electrical connection with the connector 8, the contact strip 37 being in electrical contact with the connector 7, and the contact strip 36 being in electrical contact with the connector 9. lVhenever the movable parts are in their normal positions, which are the positions indicated in Fig. '3, then 40 no contact is established between contact plate 35 and either one of the contact plates 36 or 37. When however the switch element is moved beyond this normal position in either direction circuit is established between the contact plate 35 and either the contact plate 36 or the contact plate 37.

The object of my structure will now be apparent. it for instance the arm 14; is actuated so that contact is established between the elements and 37 and the pres sure against the handle lei. then released, then the roller 29 and spring 33 restore the parts ,to the position shown in full lines in r Fig. If however the arm l4v is moved in a clockwise direction to establish contact between the contact plate 35 and the contact plate 353, then when pressure against the arm l4 'is released, the roller 29 and spring 33 restore the parts as indicated by the dotted lines in Fig. 3. llnless the arm 14 is held in a position whereby the switch element establishes contac twthgiswitch element is rotated to the normal positions int 65 dica ted in Fig. 3 so tliat contact only obtains when pressure is "exerted against the arm H to hold itin either one of its farther most positions. It will be obvious however that the arm 14: is arranged to occupy either one of two normal resting positions, and the resting position which the arm occupies-is for the purpose of indicating with which particular plate, that is, 36 or 37 contact has been last established. Thus if contact has been established bet-weenthe plates 35 and 37 and pressure against the handle is released, then automatically the parts resume the position shown in full lines in Fig. 3 to indicate that contact has last been established with plate 37. f

I have thus provided a switch structure in which two different circuits, for-instance, may be established, which switch structure at the same time has means to indicate which circuit was the one last established or otherwise controlled.

It will be .apparent that although the handle 14 may be moved from one indicating position to the other. without effecting the closure of either of the contact plates 36, 37 this is not the intended operation of the device as the intermediate indicating positions are provided for the purpose of indicating to which extreme operating position theswitch was last moved.

I have thus'set forth one form which my invention may take, but it will be readily apparent that changes and modifications maybe made without departing from its spirit.

Having-however thus described one form for illustrative purposes, what I claim as new and desire to secure by Letters Patent is:

1. A switch device comprising a recipro catable actuating member having four posi tions, said positions being two extreme operative positions and two intermediate indicating positions. switch contacts for each of said extreme positions, a wiper controlled by said actuating member torengaging said contacts, said actuating member being adapted to be manually moved into either extreme operative position, and means whereby when the operator releases the hold upon the actuating member when in either operative position it. is automatically restored to an intern'iediate indicating position. 2.
